Chip’s Challenge, the 1989 top-down tile-based puzzler created by Chuck Sommerville, is heading to Steam along with the unreleased sequel Chip’s Challenge 2.

After the release of the first game, Sommerville spent two years developing the sequel, only to find the trademark had been sold. The trademark’s new owners wanted him to fund the publishing, which he couldn’t afford resulting in Chip’s Challenge 2 being put on the shelf.

“When I couldn’t release Chip’s Challenge 2, it hit me really hard. Not only had I spent two years perfecting it, I also felt I’d let down the fans too.” Chuck Sommerville said in the press release. “I generally thought the only way Chip’s Challenge 2 was ever going to see the light of day was by having my wife leak it on the internet upon my death.”

Now, two decades later and five years worth of negotiation with the trademark owners, Chip’s Challenge 2 will be released on Steam in its original form alongside its predecessor.

Trading Cards and Steam Workshop are being added to the original code along with game saves instead instead of “the old code system.”

Originally released for Atari’s Lynx hand-held system, Chip’s Challenge was eventually ported other formats such as DOS, Windows, Amiga, Commodore 64 and the ZX Spectrum.
